The invention consists in the novel construction, arrangement andcombination of parts as will be hereinafter fully described and definedin the appended claims.

In the accompanying drawing in'which similar reference characters denotecorresponding parts, Figure 1 is a side elevation of my device showingits attachment to a shoe; Fig. 2 is a perspective view of thedevice;Fig. 3 is a section on line 3-3 of Fig. 1, Fig. 3 is a front view of adetail; and Fig. l is a perspective view of a somewhat modified form ofthedevice.

My device is adapted to be used principally in connection with a shoesuch as originally used for bathing but may with slight modifications bemade applicable to the hands. 7

When used in connection with shoes, the latter, as will be hereinafterdescribed, are. equipped with means for the attachment of the device.
